I'd like to BPF_PERF_OUTPUT() at a high rate (>1000/s), and have these
buffered and read in groups by bcc. But the typical loop we're using:
b["events"].open_perf_buffer(print_event)
while 1:
b.kprobe_poll()
Wakes up as quick as it can, without much buffering. Lots of context
switching.
I can fix it by inserting a delay:
b["events"].open_perf_buffer(print_event)
while 1:
sleep(0.1)
b.kprobe_poll()
Am I crazy? This does seem to work.
